Question

How many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water?

Answer 1

Answer:

The number of 1/5 liter glasses that Lin can fill is $7\frac{1}{2}$

Step-by-step explanation:

we know that

To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5

so

$1\frac{1}{2} :\frac{1}{5}$

Convert mixed number to an improper fraction

$1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}$

substitute

$\frac{3}{2} :\frac{1}{5}$

Multiply in cross

$\frac{5*3}{2*1}=\frac{15}{2}=7.5$

Convert to mixed number

$7.5=7+\frac{1}{2}=7\frac{1}{2}$
